Product Details
The MAX4188/MAX4189/MAX4190 operate from a +5V single supply or from ±2.25V to ±5.5V dual supplies. These amplifiers consume only 1.5mA per amplifier and are capable of delivering ±55mA of output current, making them ideal for portable and battery-powered equipment.
The MAX4188/MAX4189/MAX4190 have a high-speed disable/enable mode that isolates the inputs, places the outputs in a high-impedance state, and reduces the supply current to 450µA per amplifier. Each amplifier can be disabled independently. High off isolation, low switching transient, and fast enable/disable times (120ns/35ns) allow these amplifiers to be used in a wide range of multiplexer applications. A settling time of 22ns to 0.1%, a slew rate of up to 350V/µs, and low distortion make these devices useful in many generalpurpose, high-speed applications.
The MAX4188/MAX4189 are available in a tiny 16-pin QSOP package, and the MAX4190 is available in a space-saving 8-pin µMAX® package.
